BINDER-FRAME.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed September 17, 1903. Serial No. 173,509.

To all whom, it concern.-

Be it known that I, WILLIAM J. VATTERS, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Binder Frames, of whichthe following is a specification.

This invention relates to loose-leaf binderframes; and its object is toprovide a strong and substantialframe adapted to be easily and quicklyadjusted without buckling or getting out of order otherwise under thestrains to which it is subjected and which can be made inexpensively ofcomparatively few parts.

In the drawings I have illustrated several embodiments of the invention,and referring thereto, Figure 1 is a plan view. Fig. 2 is a similar viewshowing a different construc tion. Fig. 3 is also a plan view showing aconstruction in which the travelers are at the ends of the screw-rodwhen the frame is closed. Fig. 4 is a sectional view on the line 4 4 ofFig. 3. Fig. 5 is a sectional view on the line 5 5 of Fig. 3. Fig. 6shows a rightthreaded screw for operating two travelers. Fig. 7 is adetail view.

In the drawings like numerals of reference designate corresponding partsin the several figures, and referring thereto, 10 is a back member and 11 represents relatively movable members, to which the covers (notshown)are attached. These members are provided with interfitting ends ofsuitable construction, the drawings showing the ends 12 on the movablemembers arranged to work within and close to the ends 13 on the backmember, and thus constructed these ends act as guides for the movablemembers and assist in maintaining the members in proper. relativeposition. The movable members are adjusted relatively by a screw-rod 14,which is suitably mounted in bearings 15 on the back member and shapedat one end 16 to receive an operating-key. (Not shown.) This rod carriesone or more threaded travelers 17, which project on either side thereofand are operatively connected to the movable members'to move saidmembers relatively as the traveler is moved on and by the screw-rodlongitudinally of the frame. The traveler carries pins or rollers 18,which are arranged to work in oppositely-directed guides on the movablemembers. These guides cross each other and are preferably in the form ofgrooves or slots 19 in triangular plates 20', attached to and formingpart of It will be readily unthe movable members.

derstood that as the traveler moves on the screw-rod its guide-pins orrollers working in slots 19 will operate to move the movable membersrelatively, and thus extend or contract the frame, as desired.

My invention may be embodied in different specific forms, some of whichI have shown in the drawings.

In Fig. 1 two travelers are mounted on a right and left threadedscrew-rod 14 and operatively connected with the movable members byengaging slots in two sets of over lapping triangular guide-plates 20,which have their apices 21 inwardly directed.

In Figs. 3 and 6 the constructions are substantially the same as in Fig.1, except that in Fig. 3 the guide-plates are arranged with their apicesoutwardly directed, and in Fig. 6 the guide-plates are arranged withtheir apices pointing in the same direction and with the screw-rodright-threaded only. I may bend over the base 22 of one guide-plate toform a channel-guide groove to receive the base of the other guide-plateto maintain the members in proper relative position. Strips 23 may befastened to the back member and arranged to engage the movable members,as shown in Figs. 2 and 3, if desired, to further assist in maintainingthe relative position of the members.

In Fig. 2 a single traveler and set of cross guide-plates therefor areshown located at one end of the frame, and at the other end toggle-arms24 are connected to the movable members and to a sleeve 25, movablymounted on the screw-rod and having connections.

26 with the traveler. In this construction the movable plates are movedrelatively by travelers working in the guide-slots, as heretoforedescribed, and the toggle is simply employed to insure the even andregular movevided with a slot 28 to receive an antifrictionroller 29 onthe other plate.

Without limiting myself to the exact construction and arrangement ofparts herein shown and described, what I claim, and desire to secure byLetters Patent, is

1. A binder-frame comprising two movable members, two guides carried bysaid members and crossing each other, and means for moving said guidesrelatively to move said members away from or toward each other.

2. A binder-frame comprising two movable members, guides carried by saidmembers and crossing each other, and means for changing the point ofcrossing of said guides to move said members away from or toward eachother.

3. A binder-frame comprising two movable members, guides carried by saidmembers and crossing each other, a traveler movable on said guides, andmeans for moving the traveler to change the point of crossing of saidguides and move said members away from or toward each other.

4. A binder-frame comprising a back member and two relatively movablemembers, guides carried by said movable members and crossing each other,a traveler movable on said guides, and a screw-rod mounted on said backmember adapted to operate said traveler to change the point of crossingof said guides and move said movable members away from or toward eachother.

5. A binder-frame comprising two relatively movable members, guidescrossing each other and carried by said members, a traveler movable onsaid guides, and means for moving said traveler at a right angle withthe line of movement of said movable members.

6. A binder-frame comprising a back member and two relatively movablemembers, a pair of overlapping guide-plates on said movable membersprovided with oppositely-directed slots, a traveler working in saidslots to move the movable members away from and toward each other, andmeans for moving the traveler.

7. A binder-frame comprising two relatively movable members, a pair ofoverlapping guide-plates on said members at each end of the frame, saidplates having oppositely-directed guide-slots, travelers working in saidguide-slots, a back member, and means connected to said back member foroperating said travelers to move the movable members bodily away fromand toward each other.

8. A binder-frame comprising a back member and two relatively movablemembers, overlapping triangular guide-plates on said movable membersprovided with oppositely-directed guide-slots, a traveler working insaid'guideslots, and means for moving the traveler longitudinally of theframe to move the movable members bodily away from and toward eachother.

9. A binder-frame comprising a back member and two relatively movablemembers, triangular guide-plates carried by said movable members withtheir bases overlapping, a channel on the base of one plate forming aguide for the base of the other plate, guide-slots in said plates, atraveler operatively engaging said slots, and means for moving thetraveler.

10. A binder-frame comprising a back member and two relatively movablemembers, a set of overlapping triangular guideplates carried by themovable members at each end of the frame, oppositely-directed slots insaid guide-plates, travelers working in said slots, and a screw-rod formoving said travelers longitudinally of the frame to move the movablemembers bodily away from and toward each other.
